実験手順
Trifluoroacetic Acid (20 ml) added to a mixture of Water (2 ml) and 7-((3aS,4R,6R,6aR)-6-(((3-(2-(5-bromo-1H-benzo[d]imidazol-2-yl)ethyl)cyclobutyl)(methyl)amino)methyl)-2,2-dimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl)-N-(2,4-dimethoxybenzyl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine (0.9 g, 1 mmol) at RT. The reaction mixture was stirred for one hour, Triethylsilane (0.39 ml, 2.4 mmol) was added. The volatiles were removed in vacuo and resulting residue was purified twice by flash chromatography (DCM/7N NH3 in MeOH 87:13). The residue was taken up in MeOH/H2O (5:0.5 ml) and K2CO3 (100 mg) added. The mixture was stirred for 1 hour, then concentrated and purified by flash chromatography (DCM/7N NH3 in MeOH 87:13) to give the desired product (0.15 g) as an off-white foam/gum. cyclobutyl)(methyl)amino)methyl)cyclopentane-1,2-diol (0.15 g; 20%) as an off-white foam/gum.
